As a free and open source anti-censorship tool, Lantern uses strong AES-256-CBC encryption to enable access to any blocked websites, including Netflix. Lantern is available for Mac OSX, Linux and Windows. Like Lantern, Psiphon is a free Android app and utilizes robust technologies including VPN, SSH and HTTP Proxy to circumvent government censorship in countries such as China. Although its VPN speeds are shifty at best, Psiphon’s best draw lies in its use of several protocols, allowing users to switch in the event that one protocol is blocked.
At the core of it, Opera is more of a proxy service than it is a VPN, so using this client does not protect BitTorrent downloads and online activities conducted outside the Opera browser.
While Opera has no data limits and offers impressive speeds, it has a limited server network and collects some logs, which puts to question its ability to provide solid online security and anonymity.
